Abstract :
A novel algorithm for adaptive pattern null synthesis which is based on the Gram-Schmidt orthogonalization is proposed. It uses the element nulling vector method which not only maintains all the advantages of pattern null synthesis but also has a small increase in the pattern sidelobe level for suppressing the wideband clutter and setting up a wide notch. Compared with the original algorithms, when setting up the same null notch, the sidelobe level decreases by about 3~5 dB. Numerical result comparisons between this algorithm and the original ones are given
